John McEnroe swapped his role as a Wimbledon commentator for a stint as a chauffeur driver, surprising two unsuspecting tennis fans with an unique journey to The All England Club.

Three-time Wimbledon winner McEnroe plays the role of The Secret Chauffeur in Jaguar's #FeelWimbledon video, surprising fans Tom Payne and Nick Webb, who were selected to take part in the Secret Chauffeur stunt and offered a VIP trip to Wimbledon. On route to Wimbledon, the real chauffeur jumped out the car to be replaced by McEnroe as he took hold of the wheel and personally drove the two unsuspecting fans down to The Championships, Wimbledon. It comes as part of Jaguar Land Rover's role as official car supplier to the championships.

Jaguar is using sociometic, biometric and atmospheric sensors to analyse and celebrate the unique spectrum of emotions associated with the world's number one tennis tournament. Documenting The Secret Chauffeur experience, Jaguar captured the emotional reactions of Payne and Webb using biometric wristbands.

Results from the wearables, which are measuring the heart rate of selected fans every day during Wimbledon, shows both Payne and Webb's heart rate increased dramatically when McEnroe switched as their driver. When McEnroe was revealed, Tom Payne's biometric wearable device showed his excitement and heart rate which increased by 60.3 per cent to 93 bpm. It continued to rise as the fans quizzed McEnroe on his thoughts about Murray's chances to win a second Wimbledon title, and posed for photographs with the American tennis legend outside the famous gates to the world's best tennis tournament.

Before resuming his media duties for the day, McEnroe, said: "I was very happy to be part of this creative stunt with Jaguar. This is the greatest Grand Slam of them all - both in the eyes of the players and fans - and the surprise on Tom and Nick's faces when I got in the car shows just how excited the fans get at Wimbledon."

Tom Payne said: "I thought I was just coming to Wimbledon to watch the quarter finals and enjoy the atmosphere, but to be driven there in style by the legend John McEnroe was incredible. It was an awesome surprise!" Nick Webb added: "I think my reactions say it all! Walking into Wimbledon with McEnroe was something I'll never forget. Thank you to Jaguar for such a brilliant start to our day at Wimbledon."
